During February 2025, work focused on enhancing the bin456789/reinstall repository by implementing a region-specific optimization for the Debian installation process. The update introduced logic within the shell-based installation script to detect China-based environments and automatically switch to domestic mirrors, thereby reducing download latency and improving reliability for users in that region. This feature was integrated into the --ci installation path, aligning the installer flow with business goals to streamline onboarding and support faster deployments. The project leveraged shell scripting and system administration skills, resulting in a targeted solution that addresses regional network challenges without introducing new bugs or regressions.
